Joe Sandor and the crew from Chicago Crucible demonstrate an iron pour at Maker Faire Detroit 2011. These metalheads collected metal from old radiators and coke from a Detroit power plant and then fired up the furnace. They poured the molten steel into a watermelon and other decorative molds, which were created at the Faire. Learn more about the lost art of the iron pour.
Dangerous Prototypes made a nice post about the pour with more pictures.
